A new algorithm for the rotation of horizontal components of shear-wave seismic data

Kangan Fang, R. James Brown

Rotation of horizontal components of shear-wave data is one of the key processing procedures in anisotropy analysis. Several shear-wave rotation algorithms are available and suitable for different situations. In this paper, a new algorithm for the rotation of shear-wave data is proposed. This new algorithm can be used to rotate the horizontal components of shear-waves generated by multiple sources that have different amplitudes and wavelets in azimuthally anisotropic media. Synthetic data test and field data example showed that the algorithm are successful and robust.
